UV-Stability and Associated Failure Mechanism of Thin Film Automotive Paints 2006-01-0752

Today the technique of “primer less coating” has developed into a sophisticated method. Due to the missing primer, new parameters must be included in the quality ensuring process. One of these parameters is the wavelength-specific UV-transmission. The evaluation of the necessary film thickness is another fundamental factor for the determination of the light transmittance and is directly related to the resulting cost benefit. With a combination of these two parameters the minimum film thickness of a basecoat can be determined approximately. This data in combination with further values like maximum applicable spray made, ESTA (Electrostatic Application), and popping or sagging film thickness limits, the process window can be calculated.
